Abstract
The utility model relates to an elasticity demonstration instrument used for physics teaching. The elasticity demonstration instrument comprises a bottom plate (3) and a support (4), wherein the support (4) is connected with an upper plate (6) through a hinged shaft; the upper part of one end of the upper plate (6) is provided with an integral groove (7); a weight ball (8) is arranged in the groove (7); the lower part of the other end of the upper plate (6) is connected with a spring (1) and the bottom plate (3) through another hinged shaft; a dynameter (2) is arranged between the spring (1) and the bottom plate (3); the support (4) adopts a telescopic loop bar; and the outer side of the support (4) is provided with a fastening bolt (5). The elasticity demonstration instrument can select springs with different tensions and different weight balls for demonstration according to the needs of different demonstration sites, can express the tension value and accurately calculate the relation between the elasticity value and the parabolic distance, and can conduct quantitative operation, thus deepening the understanding of the students on the physics classroom teaching and the teaching effect.
Description
Technical field
The utility model relates to a kind of physics teaching teaching aid, is specifically related to a kind of physics teaching elastic force demonstrator.
Background technology
In the prior art, when physics teaching, the elastic force of spring and the relation demonstration of distortion also do not have display instrument directly perceived, and teacher is abstract explanation, and the student accepts difficulty, and teaching efficiency is poor.
The Chinese patent publication number is CN201181537, the utility model instructions that open day is on January 14th, 2009 discloses " a kind of physics teaching elastic force demonstrator ", this utility model comprises support, expelling plate, emission basket and spring, support is connected support through hinge with expelling plate, spring one end is connected with expelling plate, the other end is connected with support, and the emission basket is arranged on the end of expelling plate.The beneficial effect that this utility model realizes is that simple in structure, demonstration is clear directly perceived, is a kind of desirable physics educational apparatus.But, the demonstration that this utility model can only be abstract, comparison that can not quantize and measurement, the student grasps and still has some difficulties.
The utility model content
The purpose of this utility model be more abstract at existing physics teaching with the demonstration of elastic force demonstrator, can not quantization operation etc. deficiency, provide a kind of can specifically demonstrate the elastic force size, can quantization operation physics teaching elastic force demonstrator.
The purpose of this utility model realizes by following technological means: a kind of physics teaching elastic force demonstrator, include base plate, support, support connects upper plate by hinge, one end top of upper plate is provided with the groove of one, be placed with the counterweight ball in the groove, the other end bottom of upper plate then is connected with spring, base plate by hinge, also is provided with force meter between described spring, the base plate; Described support is set to telescopic sleeving rod, and is provided with fastening bolt in the outside.
Described counterweight ball is provided with the different 1-10 of quality.
Described spring is provided with the different 1-10 of pulling force.
Compared with prior art the utlity model has following tangible advantage: this physics teaching can be according to different demonstration place needs with the elastic force demonstrator, select the spring and the counterweight ball of different pulling force sizes to demonstrate, and the size that can express pulling force, the accurate relation of calculating elastic force size and parabolic distance, can quantization operation, more can deepen understanding and the teaching efficiency of student to the physics classroom instruction.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-spring, 2-force meter, 3-base plate, 4-support, 5-fastening bolt, 6-upper plate, 7-groove, 8-counterweight ball.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
A kind of physics teaching elastic force demonstrator as shown in Figure 1, include base plate 3, support 4, support 4 connects upper plate 6 by hinge, one end top of upper plate 6 is provided with the groove 7 of one, be placed with counterweight ball 8 in the groove 7, the other end bottom of upper plate 6 then is connected with spring 1, base plate 3 by hinge, also is provided with force meter 2 between described spring 1, the base plate 3; Described support 4 is set to telescopic sleeving rod, and is provided with fastening bolt 5 in the outside.Be provided with like this, this physics teaching can be according to different demonstration place needs with the elastic force demonstrator, adjust the height of telescopic sleeving rod, by force meter 2, grasp the size of spring 1 pulling force, and can express the size of pulling force, calculate the relation of elastic force size and parabolic distance accurately, can quantization operation, more can deepen understanding and the teaching efficiency of student to the physics classroom instruction.
Described counterweight ball 8 is provided with the different 1-10 of quality.Described spring 1 is provided with the different 1-10 of pulling force.Be provided with like this, the utility model can select the spring 1 of different pulling force sizes and counterweight ball 8 to demonstrate, and the demonstration effect is comparison and quantization operation further.
In a word, the utility model provide a kind of can specifically demonstrate the elastic force size, can quantization operation physics teaching elastic force demonstrator.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
